The first execution mode
The key diagram of the turning motor 1 when Fig. 1 shows according to the watching from the side of the first execution mode.As shown in Figure 1, turning motor 1 comprises the motor frame 20 of tubular, and motor frame 20 inside of this tubular comprise stator, rotor of being connected to the rotating shaft 10 of lathe for driving etc.Be attached to the load-side of motor frame 20 at the load-side support 21 of the load-side supporting rotating shaft 10 of rotating shaft 10.And, the details of the internal structure of motor frame 20 is described below with reference to Fig. 2 to Fig. 4.
Turning motor 1 also comprises: the engine casing (Eng Cas) 30 of tubular, and it covers motor frame 20; And blower-casting 40, it holds the cooling fan on the load-side side face that is arranged on engine casing (Eng Cas) 30.And turning motor 1 comprises terminal box 50, is provided with the terminal block 51 of external connection terminals 52 and 53 above this terminal box 50 is held.
Engine casing (Eng Cas) 30 comprises and is arranged on the load offside with the first suction hole 31 of suction cooling-air, and be arranged on the load-side side face of engine casing (Eng Cas) 30 with the intercommunicating pore of blower-casting 40 internal communication.And engine casing (Eng Cas) 30 comprises the second suction hole 32 less than the first suction hole 31, and this second suction hole 32 is on the relative side face of motor frame 20 and blower-casting 40.Blower-casting 40 comprises the steam vent 46 of discharging cooling-air to the load offside.
The cooling fan of turning motor 1 drive fan housing 40 is so that cooling-air is drawn into the engine casing (Eng Cas) 30 from the first suction hole 31 and the second suction hole 32, shown in Fig. 1 empty solid arrow.
Then, be sucked into cooling-air in the engine casing (Eng Cas) 30 and be passed in the air duct that forms between the outer peripheral face of the inner peripheral surface of engine casing (Eng Cas) 30 and motor frame 20, then be discharged to the outside of engine casing (Eng Cas) 30 from the steam vent 46 of blower-casting 40, shown in Fig. 1 empty dotted arrow.
Like this, turning motor 1 will be drawn into cooling-air in the engine casing (Eng Cas) 30 via the blower-casting 40 on the load-side outer peripheral face that is arranged on engine casing (Eng Cas) 30 from the load offside, discharge towards the load offside.
The result, because can suppressing the temperature of engine casing (Eng Cas) 30 inside, load offside, turning motor 1 raises, so turning motor 1 can cool off the load that will describe the back well to side bearing 24 (referring to Fig. 2), this load is to the load offside supporting rotating shaft 10 of side bearing 24 at rotating shaft 10.
And, because turning motor 1 engine casing (Eng Cas) 30 comprise the second suction hole 32 across motor frame 20 and blower-casting 40 relative outer peripheral faces, so turning motor 1 load-side of cool motors cover 30 inside effectively.
After this, with reference to internal structure and the effect of Fig. 2 to Fig. 4 detailed description according to the turning motor 1 of the first execution mode.Fig. 2 is the partial cross section schematic diagram of the turning motor 1 during according to the watching from the side of the first execution mode.The cross section that does not comprise the assembly of terminal box 50 has been shown among Fig. 2.
The schematic diagram in the cross section of the turning motor 1 that Fig. 3 shows the line A-A from Fig. 2 according to the first execution mode when watching.The schematic diagram in the cross section of the turning motor 1 that Fig. 4 shows the line B-B from Fig. 2 according to the first execution mode when watching.Among Fig. 2 to Fig. 4 with Fig. 1 in identical assembly have identical Reference numeral.And, from simplifying the angle of accompanying drawing, omit the part of stator coil 14 among Fig. 3 and Fig. 4.
As shown in Figure 2, turning motor 1 comprises the engine casing (Eng Cas) 30 of tubular.Engine casing (Eng Cas) 30 inside hold the motor frame 20 of tubular.And, be attached to the load-side of motor frame 20 at the load-side support 21 of the load-side supporting rotating shaft 10 of rotating shaft 10 by working load side bearing 23.
On the other hand, by working load side bearing 24 is attached to the load offside of motor frame 20 to side stand 22 in the load of the load offside supporting rotating shaft 10 of rotating shaft 10.And, be provided with the external connection terminals 52 of turning motor 1 and the terminal box 50 of 53 terminal block 51 above holding and be attached on the outer peripheral face of load to side stand 22.
Turning motor 1 flows in the stator coil 14 of stator 15 electric current, generates rotating magnetic field with the inboard at stator 15.Then, turning motor 1 is by using rotating magnetic field to make rotor 12 rotations, so that rotating shaft 10 rotations.At this moment, stator 15 generates heat with this action relevantly.
Via motor frame 20 and load side stand 22 is conducted heat to side bearing 24 to load.As a result, may make load to side bearing 24 thermal deformations, load is produced harmful effect to side bearing 24.
Therefore, the engine casing (Eng Cas) 30 of turning motor 1 comprises the first suction hole 31 at its load offside, raises with the temperature of inhibition load to side bearing 24, and also comprises be used to the blower-casting 40 that holds cooling fan 43 at its load-side outer peripheral face.Blower-casting 40 comprises the steam vent 46 of discharging cooling-air to the load offside.
The inner space of the inner space of blower-casting 40 and engine casing (Eng Cas) 30 communicates with each other via intercommunicating pore 44.Be provided with from the inner space of engine casing (Eng Cas) 30 to the guider 45 of the inner space guiding cooling air of blower-casting 40 at the side face of intercommunicating pore 44.
Here, the cooling fan 43 that is contained in the blower-casting 40 is centrifugal fans, and this centrifugal fan comprises: inside comprises the fan body 41 of drive motor; With the blade 42 by using drive motor around fan body 41, to rotate.
As mentioned above, cooling fan 43 is placed on the load-side outer peripheral face of motor frame 20 or engine casing (Eng Cas) 30.In other words, cooling fan 43 is arranged on such position, and the distance of this position and load-side end is than short to the distance of side end with the load of motor frame 20 or engine casing (Eng Cas) 30.
The drive motor of cooling fan 43 drive fan bodies 41 makes blade 42 rotation, and the cooling-air that will aspirate out from the inner space of engine casing (Eng Cas) 30 via intercommunicating pore 44 thus is discharged to the load offside from the steam vent 46 of blower-casting 40.
As a result, when driving cooling fan 43, cooling-air is drawn in the engine casing (Eng Cas) 30 from the first suction hole 31 that is arranged on the load offside.Then, pass through air duct on the load-side ground of the interior mobile cooling-air of engine casing (Eng Cas) 30 from the load offside of engine casing (Eng Cas) 30 to engine casing (Eng Cas) 30, then 30 outer peripheral face is discharged to the load offside from steam vent 46 along engine casing (Eng Cas) by means of cooling fan 43, and this air duct is formed between the outer peripheral face of the inner peripheral surface of engine casing (Eng Cas) 30 and motor frame 20.
In other words, the outer peripheral face from the cooling-air of the first suction hole 31 suction along load to side stand 22 flows to load-side, then discharges from steam vent 46 via the outer peripheral face that holds as the motor frame 20 of the stator 15 of thermal source.
Therefore, turning motor 1 is from being absorbed heat by the motor frame 20 of heating such as stator 15 grades, and heated cooling-air does not flow to load to side stand 22 thus.As a result because turning motor 1 can not come cooling load to side stand 22 by overheated cooling-air before contacting with motor frame 20 by using, so turning motor 1 can effective cooling be arranged on load to the load in the side stand 22 to side bearing 24.
Because turning motor 1 can suppress load to the temperature rising of side stand 22, so for example, when the detector of the position of rotation that detects rotating shaft 10 be arranged on load to side stand 22 in the time, can prevent by the rise deterioration of the position of rotation accuracy of detection that causes of temperature.
Illustrated that in the first embodiment centrifugal fan is as cooling fan 43.But cooling fan 43 is not limited to centrifugal fan.For example, cooling fan 43 can adopt tube-axial fan.When tube-axial fan is used as cooling fan 43, tube-axial fan points to the mode of load offside with the direction of ventilation of tube-axial fan, be set to be arranged in the blower-casting 40 under the state parallel with the rotating shaft 10 of turning motor 1 at the rotating shaft of tube-axial fan.
Because be arranged in such a way tube-axial fan, so cooling-air can be drawn in the engine casing (Eng Cas) 30 from the load offside, then be discharged to the outside of engine casing (Eng Cas) 30 towards the load rightabout from steam vent 46 by means of tube-axial fan.
And engine casing (Eng Cas) 30 comprises the second suction hole 32 less than the first suction hole 31, this second suction hole 32 on the load-side side face across the relative position of motor frame 20 and cooling fan 43.Here, illustrated that the second suction hole 32 is arranged on the load-side end of engine casing (Eng Cas) 30.But, can by engine casing (Eng Cas) 30 across motor frame 20 and cooling fan 43 relative side faces groove is set, form the second suction hole.
The result, in the situation of turning motor 1, because flowing into from the outside, cooling-air do not have the side of attached cooling fan 43, and compare cooling-air with a side that flow into attached cooling fan 43 and be difficult to flow, a so side of attached cooling fan 43 and do not have the temperature difference between the side of attached cooling fan 43 to relax.Therefore, the turning motor 1 whole inside of cool motors cover 30 effectively.
Because the second suction hole 32 forms less than the first suction hole 31, so can prevent from becoming less than the air capacity of the cooling-air that aspirates from the second suction hole 32 from the air capacity of load to the mobile cooling-air of side direction load-side in engine casing (Eng Cas) 30 inside.
And, turning motor 1 from engine casing (Eng Cas) 30 absorbed inside hot cooling-air from steam vent 46 along engine casing (Eng Cas) 30 the mandatory load offside that is discharged to of outer peripheral face.As a result, turning motor 1 can prevent the load-side thermal deformation of machine tool owing to discharging cooling-air from steam vent 46.
As shown in Figure 2, the terminal box 50 of turning motor 1 is staggered relatively with steam vent 46 on to the outer peripheral face of side stand 22 in load.The result, in the situation of turning motor 1, because load is transmitted to terminal box 50 to the heat of side stand 22, and the cooling-air of discharging from steam vent 46 by recycling cools off terminal box 50, so can by cooling load to side stand 22, suppress load to the temperature rising of side bearing 24.
And turning motor 1 comprises a plurality of the first fin 25 and a plurality of the second fin 26 at the outer peripheral face of motor frame 20, to improve the cooling effectiveness of motor frame 20.More specifically, as shown in Figures 2 and 3, the first fin 25 is arranged on the load offside outer peripheral face of motor frame 20, extends with edge and the direction of the axially parallel of rotating shaft 10.
Such as Fig. 2 and shown in Figure 4, above being arranged on, the second fin 26 is provided with on the load-side outer peripheral face of outer peripheral face of the first fin 25, along the circumferential extension of motor frame 20.
Like this, because motor frame 20 comprises a plurality of fin (the first fin 25 and the second fin 26) at outer peripheral face, so increased heat removal surface area.As a result, motor frame 20 can make cooling-air effectively absorb the inner heat that produces.
As shown in Figures 2 and 3, the first fin 25 extends the side direction load-side from the load of motor frame 20.And such as Fig. 2 and shown in Figure 4, the second fin 26 is along the circumferential extension of motor frame 20, with the outer peripheral face around motor frame 20.
Such as Fig. 2 and shown in Figure 4, in turning motor 1, cooling fan 43 be arranged to the suction face of cooling fan 43 and motor frame 20 above be provided with the part state staggered relatively of the outer peripheral face of the second fin 26.
As a result, when driving cooling fan 43, the bearing of trend of cooling-air from the first suction hole 31 along the first fin 25 flows to the second fin 26, and then the bearing of trend along the second fin 26 is drawn onto in the cooling fan 43, discharges from steam vent 46.
Like this, the first fin 25 and the second fin 26 play for the effect of cooling-air being introduced the guider of cooling fan 43.As a result, turning motor 1 can be discharged cooling-airs from steam vent 46 in that cooling-air is rested in the situation of engine casing (Eng Cas) 30 inside, with the inside of effective cooling engine casing (Eng Cas) 30.
As mentioned above, will be drawn into cooling-air in the engine casing (Eng Cas) 30 from the load offside according to the turning motor 1 of the first execution mode, discharge from load-side to the load offside towards the outside of engine casing (Eng Cas) 30.As a result, according to the turning motor 1 of the first execution mode can prevent engine casing (Eng Cas) 30 inner heated cooling-airs to be attached to load to the load of side stand 22 to 24 adverse effects of side bearing.

For this reason, the below will illustrate the shape of terminal box 60 and the flowing of the cooling-air of discharging from steam vent 46 of turning motor 1a.As shown in Figure 5, the terminal box 60 of turning motor 1a is included in a plurality of the 3rd fin 61 that extend along the direction parallel with the discharge direction of cooling-air on its outer peripheral face.
As a result, because increased the radiating surface area of terminal box 60, so can pass through effectively radiation from the heat of load to side stand 22 (referring to Fig. 2) conduction, suppress load to the temperature rising of side bearing 24.
Because the 3rd fin 61 extends along the direction parallel with the discharge direction of cooling-air, so the 3rd fin 61 plays the cooling-air that will discharge from steam vent 46 towards the effect than the guider of terminal box 60 more close load offsides guiding.As a result, because can preventing the cooling-air that contacts with terminal box 60, turning motor 1a rests near the terminal box 60, so can further improve the cooling effectiveness of the turning motor 1a that is carried out by terminal box 60.
As mentioned above, be arranged on load to position relative with the steam vent 46 of cooling-air on the side face of side stand 22 (referring to Fig. 2) according to the terminal box 60 of the turning motor 1a of the second execution mode, and comprise a plurality of the 3rd fin 61 that extend along the direction parallel with the discharge direction of cooling-air at its outer peripheral face.
The result, because improved the heat-sinking capability of terminal box 60 among the turning motor 1a, so by using terminal box 60, turning motor 1a can absorb and radiation from the heat of load to side stand 22, with cooling settings better load to the load in the side stand 22 to side bearing 24.
The 3rd execution mode
Then, with reference to the turning motor of Fig. 6 explanation according to the 3rd execution mode.The partial cross section schematic diagram of turning motor 1b when Fig. 6 shows according to the watching from the side of the 3rd execution mode.Among Fig. 6 with Fig. 1 in identical assembly have identical Reference numeral.
Turning motor 1b and the difference according to the turning motor 1 of the first execution mode are type and the setting position of cooling fan 70.In other words, the internal structure of the engine casing (Eng Cas) 30 of turning motor 1b and cooling-air flows with similar according to the turning motor 1 of the first execution mode.For this reason, the below will illustrate turning motor 1b and difference according to the turning motor 1 of the first execution mode.
As shown in Figure 6, turning motor 1b comprises the cooling fan 70 that is contained in the blower-casting 71, and blower-casting 71 is arranged on the load of engine casing (Eng Cas) 30 on the side.Cooling fan 70 is that the rotating shaft 10 parallel modes with the rotating shaft of cooling fan 70 and turning motor 1b arrange, and cooling-air is drawn into tube-axial fan in the engine casing (Eng Cas) 30 from the first suction hole 31.
Engine casing (Eng Cas) 30 comprises exhaust cap 80 at its load-side side face, by the steam vent 46 of these exhaust cap 80 formation with the discharge directional steering load offside of cooling-air.
In turning motor 1b, in engine casing (Eng Cas) 30 inside, cooling-air is low to the temperature of side end in the load of motor frame 20.Therefore, turning motor 1b preferentially cooling settings in the load of the load offside of motor to side stand 22.
Like this, because side end is comprised the cooling fan 70 of cooling-air being sent in the engine casing (Eng Cas) 30 according to the turning motor 1b of the 3rd execution mode in the load of engine casing (Eng Cas) 30, thus turning motor 1b well cooling settings load to the load in the side stand 22 to side bearing 24 (referring to Fig. 2).
For convenient, illustrated in the first execution mode and the second execution mode that blower-casting 40 is defined as covering the parts of cooling fan 43.If cooling fan 43 is considered to the assembly of turning motor 1 and turning motor 1a, then blower-casting 40 can be defined as the part of engine casing (Eng Cas) 43.
